吸盤可以(yi)有很多種，我(wo)們來看一下。

一(yi)種(zhong)利(li)用內外大氣壓力的(de)差別,吸附在物體(ti)上的(de)一(yi)種(zhong)掛件,或者是(shi)抓取物體(ti)的(de)一(yi)種(zhong)工具。

另一種(zhong)是磁(ci)力吸盤,專門用于(yu)對鐵磁(ci)性(xing)物質的吸附和固定, 大(da)多數應用在機(ji)械加(jia)工等領域.

利用(yong)吸(xi)力夾持工(gong)(gong)件(jian)(jian)(jian)的機床(chuang)附件(jian)(jian)(jian)。較常用(yong)的吸(xi)盤(pan)(pan)(pan)是磁(ci)(ci)(ci)(ci)力吸(xi)盤(pan)(pan)(pan)，一般為矩(ju)形或圓盤(pan)(pan)(pan)形。它利用(yong)磁(ci)(ci)(ci)(ci)力將鐵磁(ci)(ci)(ci)(ci)性工(gong)(gong)件(jian)(jian)(jian)吸(xi)緊，用(yong)于(yu)平面(mian)磨(mo)床(chuang)，也用(yong)于(yu)銑(xian)床(chuang)和車床(chuang), 數控機床(chuang), 加工(gong)(gong)中心等。吸(xi)盤(pan)(pan)(pan)按磁(ci)(ci)(ci)(ci)力來(lai)源分(fen)有(you)電磁(ci)(ci)(ci)(ci)吸(xi)盤(pan)(pan)(pan)和永(yong)磁(ci)(ci)(ci)(ci)吸(xi)盤(pan)(pan)(pan)兩(liang)類。①電磁(ci)(ci)(ci)(ci)吸(xi)盤(pan)(pan)(pan)：體(ti)內裝有(you)多組線圈（圖1）,通入直(zhi)流電產生磁(ci)(ci)(ci)(ci)場，吸(xi)緊工(gong)(gong)件(jian)(jian)(jian)；切斷電源，磁(ci)(ci)(ci)(ci)場消失，松開工(gong)(gong)件(jian)(jian)(jian)。②永(yong)磁(ci)(ci)(ci)(ci)吸(xi)盤(pan)(pan)(pan)：體(ti)內裝有(you)整齊(qi)排列并被不導磁(ci)(ci)(ci)(ci)材料隔開的永(yong)久磁(ci)(ci)(ci)(ci)鐵（圖2）,當磁(ci)(ci)(ci)(ci)鐵與吸(xi)盤(pan)(pan)(pan)面(mian)板上的導磁(ci)(ci)(ci)(ci)體(ti)對準時,磁(ci)(ci)(ci)(ci)力線通過工(gong)(gong)件(jian)(jian)(jian)形成閉合回路(lu),吸(xi)緊工(gong)(gong)件(jian)(jian)(jian)；當轉動手柄使磁(ci)(ci)(ci)(ci)鐵與導磁(ci)(ci)(ci)(ci)體(ti)錯開,磁(ci)(ci)(ci)(ci)力線不再(zai)通過工(gong)(gong)件(jian)(jian)(jian),即可卸下(xia)工(gong)(gong)件(jian)(jian)(jian)。

以前的(de)(de)永(yong)磁(ci)吸(xi)(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)吸(xi)(xi)(xi)(xi)(xi)力(li)比電(dian)磁(ci)吸(xi)(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)小(xiao). 但是現在磁(ci)性(xing)材(cai)料(liao)性(xing)能的(de)(de)提高和設計生(sheng)產(chan)工(gong)(gong)藝的(de)(de)提高, 永(yong)磁(ci)吸(xi)(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)的(de)(de)吸(xi)(xi)(xi)(xi)(xi)力(li)可以做(zuo)得比電(dian)磁(ci)吸(xi)(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)大. 永(yong)磁(ci)吸(xi)(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)不因(yin)通(tong)電(dian)而發熱和變形，故不影響加工(gong)(gong)精度(du)。但是也會因(yin)為磁(ci)致(zhi)伸縮有很微小(xiao)的(de)(de)變形. 另有利(li)用真空吸(xi)(xi)(xi)(xi)(xi)力(li)的(de)(de)真空吸(xi)(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)和利(li)用工(gong)(gong)件(jian)與臺(tai)面間的(de)(de)正負靜(jing)電(dian)荷相(xiang)吸(xi)(xi)(xi)(xi)(xi)的(de)(de)靜(jing)電(dian)吸(xi)(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)。這些(xie)吸(xi)(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)吸(xi)(xi)(xi)(xi)(xi)力(li)都較(jiao)小(xiao)，只適用于吸(xi)(xi)(xi)(xi)(xi)緊(jin)薄壁工(gong)(gong)件(jian)或非磁(ci)性(xing)工(gong)(gong)件(jian)等。

你需要(yao)什(shen)么樣(yang)的(de)四川吸盤，你清楚嗎。
